Output Line in Error Log

[jackdleach]

Hello,

Is there a way to determine the line that threw an error?

Thanks,

Yes, use the LAST_ERROR_LINE variable.

When an error occurs you will see these variables in the watch list:

LAST_ERROR=description of error
LAST_ERROR_LINE=line number that caused the error.

These are very useful when combined with a custom error handler which could e.g. write to a log file and/or alert you via email etc.

Got it, thanks... must have missed the _LINE in the docs (I had been using LAST_ERROR but wanted to trace where it was throwing from).

As a side note, is there a way to raise an error?

For example, I use UIAccessibleList to check the contents of a window before performing an action, and I can't find a substring in that list, I'd like to throw an error.

I can manage it easily enough using a custom SRT but an error would keep things semantic.

Well if you already have a custom error routine just call it and set LAST_ERROR to whatever you want first.
